After reading about the merits of the Banks System I had one installed on my 03. The exhaust note is terrible. It sounds like my grandfathers 300 I-6 (which is a great engine) and so far the mileage according to the dash has dropped from 13.6 to 13.1.
13.1 MPG! 
I can only dream about that kind of gas mileage!
